Looked everywhere, but couldn't find anything online that specified on how to launch the 64 bit version for windows T_T. I've deleted the x86 folder, set the launch options to "-amd64" and nadda. Anyone know how to solve this (not for linux, windows only).
Oh, my bad, couldn't tell . . . but thanks for the info. Also, would you know by chance what can help increase performance? Whenever I try to run it in 1920x1080, I always get a bad 25 fps.
